EGG-BEATER.

SPECIFICATION forming part of Letters Patent No. 261,857, dated August1, 1882.

Application led February 10, 1882. (No model.)

To all whom it may concern: Y

Be it known that I, GEORGE MASON Kr'l- TERMAN, a citizen of the UnitedStates, and residing at San Rafael, in the county of Marin and State ofCalifornia, have invented a new and useful Egg-Beater, of which thefollowing is a specification. y

My invention relates to improvements in egg-beaters in which rotation isimparted to a whip of wires ora set ot' wire loops by means of a nutwhich is caused to travel up and down upon arod carrying said wireloops, and provided with spiral feathers or a screwthread; and theobjects of my invention are to provide an egg-beater simple inconstruetion, all cranks, gear-wheels, or telescoping cylindersbeing'dispensed with, easy of operation, being worked with one hand, andad apted as well tor the mixing of refreshing beverages asforegg-beating. [attain these objects by means ot' the deviceillustrated in the accompanying drawings, in which- Figure 1 is a frontelevation, representing the normal position of the parts. Fig. 2 is asectional front elevation, showing the position of the parts when thenut has been forced down toward the whip.

Similar letters of reference are used to designate like parts throughoutthe several views.

`My device consists of a bea ter-stem or screwrod, A, provided on theupper portion of its length with spiral feathers or a screw-thread, B,and ou its lower end with the bulging Wire whips or loops C. Upon thethreaded `portion ofthe beater-stem I place the threaded nut I), havingtwo upwardly-projecting rods or standards, E E, united at their tops bythe crosshead or block F, having attached thereto the lifting-ring G. Atthe base of the screw-threadB, and above the'whip C, is formed acircular flange or collar, H, which supports the lower end of the.coiled spring I, surrounding the beater-stem, and which pressesagainstthe lower face ot' the nut D. The lower end of the spring is secured toeither the flange H or the heater-stem. In order to prevent the nut frombeing forced oft' of the beater-stem by the expansivepower of thespring, a button or cap, J, is placed upon the top of the screw-rod.rlhe upper and lower edges of the cross-head F are hollowed or roundedout, so as to accommodate the lingers of the operator, who inserts onetinger through the ring G when operating the implement.

Tile operation ol my improved egg-beater will be as follows, to wit:Theilnpilementis to be placed in the glass or cup containing thematerial which is to be beaten, the lower rounded end ot' thebeater-stem resting upon the bottom of the glass and kept in continualcontact therewith. In practice one linger is inserted in the ring G, andby pressing downward the nut D will descend upon the beaterstem A,causing it to revolve upon its longitudinal axis and compress the coiledspring I. When the spring has been compressed to such an extent that.further downward travel ot' the nut is prevented the pressure upon thecrosshead is released and the expansive power of the spring will forcethe nut back to its original position, thereby causing a reverserotation ot' the beaterstem, and thus the operation is repeated.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, 1s

In a beater or mixer for liquids or semi-liquid substances or compounds,the screw-thread l ed beater-stem A, having upon its lower end the whipor wire loops, and provided with means foraiternatel y rotating saidheater-stem in oppositedirections,consistingof thethreaded nut D,supporting the standards E E, carrying the cross-head F and ring G, andthe l coiled spring I, constructed, arranged, and operatingsubstantially in the manner as herein set forth and specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 18th day of January, 1882.
